SPECIFICATION forming part of Letters Patent N0. 772,830, dated October 18, 1904. Lppdication filed September 24, 1903. Serial No. 174,499. (No model.)

To all whom it may concern:

Be it known thatLVVILLIAM EDWIN SCIIN EI- DER, a citizen of the United States, residing at Washington, in the District of Columbiadiave invented ce tain new and useful Improvements iu Box-Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in box-making machines.

It has for its object, more especially, the making of boxes from pulp, the character of the latter, however, having no bearing whatever upon the invention; but for convenience in using the same it is stated that pulp produced from wood, papier-mch, asbestos, &c., is capable f treatment or manipulation by said invention.

It has for a further object to effect the foregoing in a direct, simple, and effective manner, and particularly with rapidity, providing for the making of boxes in large numbers in the minimum time.

Other advantages of said invention will appear in the further disclosure thereof.

Said invention consists of certain parts and combinations and arrangements thereof, substantially as hereinafter more fully disclosed,

and specifically pointed out by the claims concluding the following specification.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figures 1 and 2 are views inelevation at right angles to each other. Fig. 3 is an enlarged side elevation, parts being broken away. Fig. 4 is' a sectional eleyation, parts also being broken away. Fig. 5 is a horizontal section, with the plunger and mandrel and the followers or formers in position asin. the act of compressing the material or pulp into shape to form the sides and ends or walls and bottom of the prospective box. Fig. 6 is a similar section, with the aforesaid parts or members in their initial or inoperative position. Figs. 7, 8, 9, and 10 are views disclosing the mandrel in side and end elevation and the parts or members thereof in initial and final 'or normal position, respectively. Figs. 11,.

12, and 13 are still further views of the mandrel, core, or former, the lirst being an interior view and the latter two being sections taken on lthe hnes m .r and y y of the first, re-

spectively. Fig. 14 is an enlarged horizontal section taken on the line b b of Fig. 2, showing more particularly the mandrel-trippingbar-engaging plate. Fig. 15 is alike section taken on the line a, a of Fig. 2, disclosing more fully the mandrel-engaging plate. Fig. 16 is a perspective view of the tray or chute receiving the completed box. Fig. 1T is a broken detailed view of the dogengaged catches, holding together at certain intervals the top plate and frame, presently more fully disclosed. Figs. 18 and 19 are detail views of the mandrel cover-plate and the upper end of the mandrel modified in construction to form ribs in the bottom of the box. Figs. 20, 21, 22, and 23 are detail views of a battery-cell which may be produced by my machine; and Fig. 24 is adetail view of the lower end of the plunger.

In carrying out my invention I erect a general framework, preferably raised upon legs and comprising a base-plate 1, carrying a trough 1 around its'. edge, and depending from the center of which is a box 1", having its bottom open, except the corners, which are closed by corner-pieces 1"', suitably bolted to the outside of said box. Horizontal slots 11 are provided, one on each side of the broader sides of said box, in which operate pins fixed to corner-pieces of the mandrel, presently described. Said box is also provided with vertical slots 1, in which work pins secured to the wedge-pieces of the mandrel. Supported on said bed-plate are fixed angular uprights or bars 2, one at each corner, supporting near their upper end a frame 9. Above said frame 9 are pvoted spring-pressed catches 8, engaged by springs 8, which bear against undercut notches 8b (See Fig. 17.) Said catches normally engage and support a frame 8, to lugs 8* of which are connected other catches 8", receiving the action of stirrup-like springs 8, secured to their pivots and carrying depending rods 8, extending through apertured stop-bars 8", fixed to the frame 9, with their lower ends provided with pins or IOO the catches 18" for "dropping the mandrel.. The mandrel-supporting plate 12 when restcated immediately below and engages the bot-- tom of the box 1"; but suitable springs 12" or plunger 6b, said bars having laterally fixed 15", one of said latter frames arranged at each f side of the machine between the flanges of the barsf2. Arranged interiorly of each of said frames 15 is a lateral or end foraminous formcror follower 4, vertically disposed and lined with wire fabric or netting 4 to provide for the expressing of the excess of, moisture from the pulp while undergoing formastorage-battery jar or cell. The crosspins 16 Aof the frames 15 extend through cam-slots 4, being partially diagonal and partially straight in outwardly-extending flanges or extensions 4 of said followers or formers and into the slots 3 of the bars 2.

An operating-lever 5 is pivotally connected to and passes between upstanding bars 6, secured to a horizontal plate 6, carrying ahead thereto bevel-ended arms or dogs 7, adapted to engage the studs 8d of the catches 8. The plate 6 is adapted ,to displace the shoulders of the catches 8", which are preferably beveled on their upper edge for that purpose, said plate being adapted to seat within the frame 8, and the catches 8" being-capable of returning to their normal position after the passage of the plate 6, so as to retain said plate in connection with said frame.

From the corners of the plate 6* rods 11 extend downwardly, passing through suitable apertures in the framework, and support at their lower extremity a plate 18, which carries spring-pressed catches or bolts 18", each comprising two L-shaped fingers or arms facing each other and adapted to pass up and down on opposite sides of the spring-acted upon bars or arms 18, as shown most clearly in Fig. 14. Said plate-18'* has secured thereto an angular arm 21, adapted to operate the box-conveyer, presently described.

' The arms 18 are pivoted at their upper ends to the base-plate 1 and have shoulders 12", adapted to normally engage and uphold the mandrel-supporting piate 12, said arms being pressed inward by meansof' springs 18", arranged near the base of the framework, as shown in Fig. 1. ISaid arms 18 are provided with arcuate flattened plates 18 at their ex?4 tremities, which are adapted to be engaged by:

ing upon the shoulders of the arms 18 is loare arranged between said plate and .the base? plate to occasion the depression of said plate 12 when the arms 18 are spread to collapse' the mandrel.

' that purpose.

The mandrel or core 17 comprises four cor-: ner sections or members 17 17b 17c 17*I and four wedge sections or members 17 1'(l 17 to provide for the collapsing of the mandrei, as necessary in removmg the box after its formation. Said corner sections or members are so connected or held together as, to retain their general initial outline when col- "lapsed, as the wedge mt 'nbers or sections are partially withdrawn or dropped 'to eifect To that. end said wedge sections or members are interiorly grooved, as at 17", vertically, and angular plates or guides tion into a receptacle or box, which, among 1'17"", secured to the corner-sections, engage other purposes, may be used as an electric said grooves, but permit said sections to contract as the wedge-sections are projected or dropped. Said wedge members have pin-andslot connections, as at 12"", with the plate 12, as shown in Fig. '15, and also'with the box 1 through the slots 1. By means of said slots the wedge-sections may move downward and inward at the s ame time.

The corner-sections of the mandrel are supported on the angle-pieces 1f at the corners of the box 1b and also by pins xed' thereto engaging the horizontal slots l", the head of said pins beingv `'long enough to permit said corner-sections to shrink in together as the mandrel colla ses.

If desired, wedge-shaped'corner-pieces4 (see Figs. 4, 5, and 6) may be suitably keyed or guided in receiving-grooves in the inner edges p lof the angular bars 2 and suitably connected -to the plate 12, whereby they can be with drawn at the same time the mandrel is col- -lapsed, the withdrawal of said corner-pieces rendering the machine capable of forming cleaner and better edges on the box or receptacle.

` 'The upper end of the mandrel is covered by -a plate 14, having pendent rods 13, depending through apertures in the mandrel and the plates 12 and 18. Plate 14 is preferably perforated, so that the water pressed from the -p-ulp in forming-the bottom of the box is adapted to pass through said plate down through the center of the mandrel and collect, with the water f rom the formation of the sides.

of the box, in the trough around the base' plate, from which it passes ofi' through a suitthe water, if desired. Said rods 13 are yoked --together at their lower end, as at 13", and

have a spring tending to force them apart.

lSaid rods are provided with lateral oifsets or shoulders 1'3, which are adapted to rest upon. the plate 18 and support the plate 14 te raise fthe same 'with acompleted box to remove the` latter. When said plate 18 comes nearly into contact with the plate 12, the shoulders 13 will strike the edges of the apertures 19" in ysaid plate`12 and be forced inward, disengag- IOC:

Ixo

IIS

ing them from the plate 18, when the rods y and plate 14 will fall.

An arm 21, carried by the plate 18, is adapted to engage a pivoted lever 22, throwing in- 17 l ward one end of said lever, provided mtha 13 lateral pin 22",

ing arm 9.2", pivoted at the base of the machine and carrying the box-carrier at its upper end, thereby disposing said carrier in position to receive the finished box after it has been raised upon the plate 14. The outward movement of the arm 22 is limited by a cross-pin 23, Vcarried by a bracket 23, fixed to the machine-frame. Said carrier 20, as clearly shown in Fig. 16, is entirely open at its inner end, as is its center, so that it may pass below the box when said box is raised upon the plate 14 and permit said plate to drop while it retains the boxl upon-suitable ledges 20X along the inner side of said carrier.

In Figs. 2O and 22 is disclosed a receptacle or box provided with a series of internal cleats or upward projections .25 upon the bottom thereof, the purpose being to prevent shortcircuiting` as would otherwise be the case by the accumulation of the active material in the bottom of the jar contacting with the electrodes when said jar is used for a storage or other battery. In Figs. 18 and 19 is shown the modified form of the plate 14 and upper surface of the mandrel used for forming said cleats. lt will be noted also that the receptacle or box may be formed with lateral ril or braces, if desired, by changing the formaws l.)

Ation of the sides of the mandrel and that of the followers or formers to suit the purpose, the result of which would be the production of a box with Strong but much lighter walls, which would be particularly desirable for packing or shipping purposes.

1n operationfthe various parts of the machine being' in the positions indicated in Figs. 1 and 2, in which the mandrel is shown set or expanded and the plate 14 resting upon the top of the mandrel after the pulp for the making of the prospective box has been in' troduced into the machine around said mandrel within the followers or formers 4, the lever 5 is forced downward. The dogs 7, carried by the bars 6, engage the studs 8d of the spring-catches 8, and at the same time the 4 plate 6 engages the catches 8", forcing them outward and passing beneath them into its seat in the frame 8e, thus connecting-up said plate with' said frame while the catches 8 are forced outward by the dogs 7, leaving said frame free to move downward. As said frame moves downward it carries with it the frames 15, whose-cross-pieces 16, movingin the vertical slots 3 of the pieces 2 and the .diagonal portions of the slots 4" in the followers or v formers 4", cause said followers or formers to move inward, compressing the pulp and forming the sides of the box. Some of the pulp will be forced upward, increasing the thickness thereof in the top of the receptacle formed by said followers or formers, and

upon this the plunger 6 descends as the crossbars 16 reach the vertical portions of the camslots 4 and move down along them. The

may have splashed up upon the inner surpressing inward the upstandl plunger 'w l scrape down anybulp which I' faces of the followers or formers and will make a clean edge around the bottom of the box as it compresses the pulp forming the same.` 1f desired, the face of thel plunger may be adapted, as at 6", toemboss the bottom of the receptacle or box' being formed.l The plate 18 .being connected tothe plate 6 by the rods .11 moves down with said latter plate, the arms of the catches 18x passing along the rods 18 and out ar )und their term-inal plates 18, the springs of said c atehes allowing them to be withdrawn for that purpose, but retracting them after they havepassed the extremities of said plates 18 at the end of the downward stroke of the lever 5. At the same time the plate 18 is passing the plate 18" of the rods 18 the lugs near the extremities of the rods 18 Y are pressed inward by the edges of the apertures in said plates 18", through which they pass, and as the latter plate descends past said lugs they spring out again, so that they will engage said plate, as shown in Fig. 14. on its upward movement. On the upward stroke of the lever 5, carrying with it the plate 6, the frame 8, frames 15, andthe plate 18 while the cross-bars 16 of said frame 15 are moving upward in the vertical portions of the cam-slots 4 the arms of the catches 18'Lb on theplate 18 engage thev inner faces of the plates 18ab and spread the rods 18, releasing the plate 12, which drops, carrying with ,it the wedge-sections of the mandrel and collapsing the latter. As the lever 5 continues its upward movement," car rying with it the mechanism above noted as controlled thereby, the cross-pins ofthe frame 15 travel in the diagonal portions of the slots 4, retracting the followers or formers, leaving the finished box free to be removed, At this point in the operation the lugs 13 will. be engaged by the plate 18?L and the rods 13 with the plate 14, fitting below the bottom of the completed. box and above the top of the mandrel., will be carried upward, elevating the box. As the frame 8 reaches the prescribed height it will be engaged and upheld by the catches-8 and the' catches 8x will be withdrawn by their rods engaging the stopbars 8b, thus releasing the plate 6 and allowing it to move upward without thc frame 8. When the box has reached a point above the frame 8, the arm 21, carried by the plate 18, engages the inner end of the lever 22, forcing the outer end of said lever inward and bringing the carrier l 20 inward below the box. Vhile said carrier is retained in position below the box-that is, while the end of the arm 21 is traveling acrpss the inner end of the le ver 22-the plate 18'i comes in contact with the plate 12, releasing the rods 13 from the plate 18, allowing the plate 14 to fall and leaving the box upon thecarrier, which as soon as the end of the arm 21 passes the end IOO of the lever 22 will be carried outward gravity and deliver the box from the machine. During the completion of the upward stroke the plate 18 carries the plate 12 upward and seats it upon the shoulders 12x of the arms 18, thereby settingor expanding the mandrel, when the machine is ready for the making of another box by repeating the operation just described.

It is observed that any form orcontour of box, barrel, or cask for any purpose may be made by my machine by accordingly adapting the end and lateral wall formers and the mandrel or core to that end. It will be understood that I do not limit myself as to details herein, as they may changed as circumstances suggest without departingr from the spirit of my invention and said invention remain intact and be protected.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
